Application diagrams and additional information
Two possible application diagrams are shown. The first
(see Fig.9) shows the best case: the lowest component
count. The second (see Fig.10) shows additional
components which may be necessary. Two capacitors are
added to meet EMC requirements (one on the V
second one between the set and feedback input pins).
A third capacitor has been added across the motor to
suppress current spikes. The given values of these
capacitors have to be optimized by experiments carried
out on the total application. The resistors do not have to
have the same value. The voltage hysteresis is set by
means of R

The resistor in the feedback input line (R
limit the current during the transients as illustrated in Figs 7
and 8. This resistor should have a value larger than 2 k .

2 k . A diode is placed in series with the supply line in both
applications to protect the device from reverse polarity
switching and from damage caused by pulses 1 and 3 in
Figs 7 and 8. In the present application a varistor is
included in the motor. The electrolytic capacitor of 47 F
should have a very low ESR, for instance as low as 5
a temperature of 40 C. An extra ceramic capacitor
(approximately 100 nF) parallel to it is obligatory when this
can not be guaranteed.
